So there are so many movie trilogies out there, but which is the best?
I would pick Lord of the Rings, with the original Star Wars closely behind. LotR had everything from a great story, amazing characters, and some great special effects, not to mention the two best battle scenes of all time (Minas Tirith and Helms Deep). I don't think any trilogy will ever beat LotR.
The origional Star Wars trilogy definately. The first Pirates movie was great, but I didn't like the last two. Some other good trilogies: Back to the Future and Indiana Jones (soon not to be a trilogy).
